Application July 23,

4 Claims.

An important objectof the invention is to provide such a device embodying a. seriesof settling compartments and dividing means separat ing the compartments and co-nstructed'to form obstructive filtering devices whereby a liquid may beconditioned as an incident to passage through the filtering device.

Another importantobject of the invention is toprovide such a device having traps or pockets wherein light and heavy particles of matter may be isolated.

Other objects such as the economy of construction, the accessibility for cleaning and renewal of parts upon occasion, and the arrangement of the parts which facilitates self cleaning action with respect to the obstructive filtering devices, will be apparent as the invention is better understoodfrom the following description, which, taken in connection with the accompanying a preferred embodiment thereof.

Referring to the drawing;

Figure l is an elevational view of a device embodying my invention.

Figure 2 is a transverse sectional elevation taken substantially on line 2-2, in Figure 1, and illustrating details of construction. I

Figure 3 is a. longitudinal elevational section taken substantially on line 3-3, in Figure 2, fur- 35theri1lustrating details of construction.

Figure 4 is a fragmentary section taken substantially on line 4-4, in Figure3 and illustrating the sump pockets and the means of support for the obstructive filtering devices in one of the 40 body parts.

Figure 5 is a perspective view of the portion ofthe'body part shown in Figure 4, and;

Figure 6 is a detail view of one of the obstructive filtering devices.

To'illustrate -myinvention I have shown a body formed of companion parts and I2, of similar form suitably secured together by means of threaded screws I3, and transversely divided to form a series of settlement compartments M, 50 I5, I6, H and I8, by means of dividers I9, 20,

2| and 22. v

The body may be formed of. any two parts adapted to form an enclosure and in the present embodiment I have shown the parts I! and |2,

' 55 molded or cast to similar form and so that when .1936, Serial No. 92,180

secured together as shown in (Figures 1, 2 and 3) an oblongchamber is formed. The part II, includes a top wall 31, side walls 32 and 33, end walls'34 and 35; and an abutment flange 3's located at the extremities of the walls 32, 33, Mand 35,:an'd extending laterally therefrom. The part i2 similarly-includes a bottom wall 4|, side walls &2 and 43. end walls 44 and 45, and an abutment flange 46-.

A suitable sealing gasket 41 is arranged between =theabuttingfianges 36 and 46, and, as above mentioned, the-parts H and H. are secured together by means of the screws 63 which extend through suitable apertures in the wall 4| of thepart i2 and have'threaded engagement in threaded bosses 48 extending from the wall 3| of the part H. The heads of the screws |3-may becountersunkbelow the surface of the wall 4| and suitable gaskets &9 may be provided to prevent leakage.

In accordance with this invention the body is divided transversely by means of the dividers 19;" 2o; 2| and 22 as above described and to provide a 'means for locating andsecuring these dividers; spacedand substantially parallel webs 5| are formed to extend from the walls 3|, 32 and 33 of the body part H, and corresponding webs 52 are formed to extend from the walls 4|, 42 and 43 of the body part I2 in alignment with the webs 5i in-the bodypart- The webs 5| and 52 being spaced to form a pocket in which one of the dividers may be interlookingly engagedupon the assembly of thebody parts H and I2. These websarearranged at intervals along the body so:

that when the dividers are assembled in the body it is divided thereby into the separate settlement compartments-i4, H5, I6, I! and I8.

The webs 5| and 52 are relatively high so that asub'stantial sediment sump 58' or pocket is formed in the bottom of each one of the compartments l4, l5, 16, I1 and |8'for the accumulation of heavy particles of matter or sediment and'a similarpo'cket 59 is formed at the top of each one of" said compartments wherein foam and particles of matter of less specific gravity than the liquid to be conditioned may be collected. Longitudinal webs 6| are or may be formed in the sump or pockets 58 and 59 as indicated to minimize the effect of any transverse or rotary movements, of the liquid being conditioned, with respect to materials contained or collected in the pockets 58 and 59.

The dividers I9, 20, 2| and 22 may be any suitable obstructive filtering devices capable of obstructing the passage of solid particles of matter such as a mesh fabric or a porous or pervious material or a suitable combination thereof. In the present embodiment I have shown (Figs. 2, 3 and 6) such a device formed of a wire mesh fabric, part 62, suitably mounted in a rigid frame 63 of suitable metal. The frame 63 is shaped to fit in between the webs 5| and 52 and to be rigidly interlocked therein upon the assembly of the body parts I! and I2, asillustrated (Figs. 2, 3 and 4). Suitable reinforcing webs such as a web 64 extending across the mesh 62, may be provided for reinforcing the mesh.

In order to distribute the filtering action the gage of the mesh 62 is progressively varied from a relatively course mesh in the divider I9 to a relatively fine mesh in the divider 22.

Liquid to be conditioned is admitted to the compartment or sediment chamber l 4 from a tube line 65 connectedto the body part II by means of a tube fitting 66 having threaded engagement in a boss 61 formed therein. The liquid then passes successivelythrough the series of settlement compartments for conditioning and is then discharged Suitable mounting screws 14 and 15 may be cast into the body part I l as inserts and to facil-" itate the attachment of the body to a machine through support brackets 76 and TI as indicated (Figs. 1, 2 and 3).

Due to the relatively large capacities of the sediment chambers l4, l5, l6, l7 and I8 in proportion to the inlet and outlet tube lines 65 and H the flow of liquid between compartments is relatively slow and permits any particles of foreign matter to either precipitate into one of the sumps 58 or.

to fioat into one of the pockets 59. Forward movement of the particles is also obstructed by the dividers i9, 20, 2! and 22 in accordance with the mesh of the screens 62 mounted therein so that the finer particles are allowed a more extensive period of time to settle or float out whilethe more coarse particles are allowed a shorter period of time. a

When a device embodying this invention is attached to an automobile engine road irregularities tend to set up arotary flow of the liquid Within the filtering device and about the longitudinal axis thereof. This rotary fiow is beneficial because it effects a washing action at the surfaces of the dividers I9, 20, 2 I, and 22 and the longitudinal webs 6| reduce the effect of this action in the sumps 58 so that. the accumulated sediment will not be washed therefrom.

It will be noted that the body may be readily I dissembled for cleaning or replacement of parts by the simple operation of removing the screws I3 and separating the parts H and I2.

It is thought that the invention and many of .its attendant advantages will be understood from vention, or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
